[Conventional technology]

When designing a large-scale system, it is possible to distribute the functions by modularizing each function and calling the module, or to create an independent system (lower system) that has already been designed as if it existed under the own system (upper system). By calling and executing the module as if it were a module, it is possible to distribute functions and reduce the load on daily life.

In the latter case, when executing the processing of an independent lower system, the lower seven systems are called from the higher system, and control is also transferred from the higher system to the lower system, and after the processing is completed, control is returned to the higher system. .
